Simultaneously foldable multi-screen monitor arm device

ABSTRACT

A simultaneously foldable multi-screen monitor support having separate support arms connected to separate posts extending from a base. The posts are mounted on end sections of the base and are pivotable about a center section. When one post is moved between a first position and a second position, the other post simultaneously moves between a third position and a fourth position. The movement of one post moves the other post and monitors that are supported on the posts are moved in the same manner from a folded position to an operating position or vice versa.

CROSS-REFERENCE TO RELATED APPLICATION

This application claims priority from U.S. Provisional Patent Application No. 61/718,511, filed Oct. 25, 2012, the disclosure of which is hereby incorporated by reference in its entirety.

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to a simultaneously foldable multi-screen monitor support and more particularly to a monitor support having two or more monitors mounted on separate support arms that are movable between a folded position and an operating position. When one monitor on one support arm is moved between the folded position and the operating position, the other arm simultaneously moves between the same two positions for the other arm.

2. Description of the Prior Art

Monitor supports for two or more monitors are known. The Chih U.S. Patent Application Publication No. 2008/0225472 describes a dual display device in which the monitors move apart from one another or toward one another. The monitors are mounted on a single post.

The Jeong U.S. Pat. No. 7,529,083 describes a monitor support apparatus in which two monitors are mounted on support arms extending from a single post.

SUMMARY OF THE INVENTION

It is an object of the present invention to provide a monitor support that has monitors supported on it, and a plurality of posts that each extend from a base, the monitors being movable simultaneously from a first position to a second position by moving one of the monitors.

A support for at least two monitors comprises a base, the base having a center section and two end sections pivotally connected thereto. The center sections and two end sections have gears therein that are arranged to interact with one another to pivot the end sections relative to the center section in a synchronous manner. The end sections each have a post mounted at or near a free end thereof, the post extending upward from the free end of each end section. There are two posts, each post having a support arm movably mounted thereon, each support arm having a monitor mounted thereon. The gears interact so that when one of the posts is moved from a first position to a second position, the other post simultaneously moves from a third position to a fourth position.

In the arrangement of gears shown in the drawings, when one post is pivoted clockwise, the other post pivots by an equal distance or angle counterclockwise and vice versa. In a further embodiment, a support can have more than one monitor mounted on each post. Additional monitors can be mounted on additional support arms or on a single support arm on each post.

There are many uses for the monitor support of the present invention. One use occurs when the monitor support is mounted on a wheeled cabinet or other mobile device. When it is desired to use the monitors, the monitor support can be moved to the operating position, preferably, when the wheeled cabinet or other mobile device is stationary. When the wheeled cabinet is about to be moved to a new location, the monitors can be returned to the folded or storage position. For example, in hospitals or other health care facilities, computer processors or monitors are often mounted on a movable device or platform and move from room to room. During transit from room to room, the monitors are preferably moved to the folded or storage position to protect the monitors from damage. Also, it is much easier and more efficient to wheel the monitors through doorways and hallways when the monitors are in a folded position. Further, when a user has multiple monitors on a stationary work surface, the user may wish to have the ability to easily move the monitors from an operating position to a folded or storage position when the monitors are not being used in order to create additional space on the work surface.

While it is not shown in the drawings, while a preferred operation is for the gears to move the monitor supports in opposite directions, the gears can be designed to move the monitor supports in the same direction where that result is desirable.

DETAILED DESCRIPTION OF AN EMBODIMENT

In FIGS. 1 and 2, a monitor support 2 has a base 4 with a center section 6 and two end sections 8, 10. End sections 8, 10 each have an insert 12, 16 located at or near a free end 14, 18, respectively. Posts 20, 22 are mounted in the inserts 12, 16 and extend upward from the end sections 8, 10, respectively.

Monitor arms 24, 26 are movably mounted on the posts 20, 22, respectively, by clamp members 21, 23. Mounting brackets 28, 30 connect the mounting arms 24, 26 to monitors 32, 34, respectively. The mounting brackets 28, 30 may be of conventional design, so as to allow the monitors 32, 34 to be independently adjusted in vertical and horizontal planes. Each mounting bracket 28, 30 is connected to a mounting arm 24, 26 in a T-shaped channel 36, 38, respectively. The monitor mounting brackets 28, 30 may be of conventional construction and allow the monitors to be moved vertically and horizontally relative to the monitor arms 24, 26 to which they are connected. The monitors 32, 34, as shown in FIGS. 1 and 2, are in an operating position, being mounted beside one another with a front 38 of each monitor 32, 34 facing outward and forward.

In FIG. 2, it can be seen that the end sections 8, 10 have gears 40, 42, respectively, at an inner end thereof and that there are two circular shaped gears 44, 45 located between the gears 40, 42 in the center section 6.

In FIG. 3, the monitor arms 24, 26 are angled slightly toward one another as the end sections 8, 10 are angled slightly outward from one another. This would place the monitors in an operating position that is slightly different than the operating position of the monitor shown in FIGS. 1 and 2, where the end sections 8, 10 are substantially perpendicular to the center section 6.

In FIG. 4, the monitors 32, 34 are shown to be in a folded or storage position with the end sections 8, 10 being substantially parallel to the center section 6 and the monitors 32, 34 facing one another. The posts 20, 22 are in first and third positions, respectively, when in the storage position.

In FIG. 5, there is shown an enlarged perspective view of the gears 40, 42 of the end sections 8, 10 and two circular gears 44, 45 located between gears 40, 42. It can be seen that the gears 40, 42 are integral with the end sections 8, 10, in this example being integrally formed with the end sections 8, 10. The four gears 40, 42, 44, 45 are pivotally mounted in the center section 6 to interact with one another. A cover 46 of the center section 6 may be transparent to expose the gears 40, 42, 44, 45, if desired.

In FIG. 5, the end sections 8, 10 are in the operating position relative to the center section 6, and the posts 20, 22 are in second and fourth positions, respectively. As the end section 8 is manually pivoted in a clockwise direction toward the storage position when viewed from the top, the gear 40 will interact with the gear 44, which in turn interacts with the gear 45, which in tum interacts with the gear 42 to cause the end section 10 to pivot counter clockwise. The gears 44, 45 are identical to one another and it will be understood that the end section 10 alternatively could have been pivoted in the counter clockwise direction to cause the end section 8 to pivot in the clockwise direction toward the storage position.

FIGS. 6 to 8 show additional views of the monitor support 2, including optional mounting hardware extending from a bottom of a lower member 48 of the base 4 for mounting the monitor support 2 to a work surface.

FIG. 9 shows a partially exploded perspective view of the monitor support 2. The center section 6 of the base 4 has washers 50 located on either side of the gears 40, 42 of the end sections 8, 10, respectively, as well as washers 52 located on either side of the gears 44, 45. The base 4 includes fasteners, and pivot pins or shafts that pivotally connect the end sections 8, 10 and gears 44, 45 to the cover 46 and lower member 48 of the center section 6 of the base 4.

In operation, the monitor support 2 can be moved from the folded or storage position shown in FIG. 4 with the posts 20, 22 in the first and third positions, respectively, to an operating position, such as is shown in FIGS. 1-3 and 6-8, simply by applying force directly or indirectly in an appropriate direction to one of the end sections 8, 10, or posts 20, 22, which will cause the gears to interact to simultaneously pivot the other end section, simultaneously. Therefore, a user can move the monitors to the operating position, the folded position or any intermediate position, with one hand. While manual operation is preferred, a motor (not shown) operated through a remote (not shown) or by a controller on the support itself (not shown) can be connected to rotate one of the gears, thereby causing the remaining gears to rotate in a corresponding manner to move the monitor support between the operating and folded or storage positions.
